$(function() {
$('.story-small img').each(function() {
var maxWidth = 100; // Max width for the image
var maxHeight = 100; // Max height for the image
var width = $(this).width(); // Current image width
var height = $(this).height(); // Current image height
// Check if the current width is larger than the max
if(width>height && width>maxWidth)
{
ratio = maxWidth / width; // get ratio for scaling image
$(this).css("width", maxWidth); // Set new width
$(this).css("height", height * ratio); // Scale height based on ratio
}
else if(height>width && height>maxHeight)
{
ratio = maxHeight / height; // get ratio for scaling image
$(this).css("height", maxHeight); // Set new height
$(this).css("width", width * ratio); // Scale width based on ratio
}
});
});

In your html you can pass in an array for the name i.e
<input type="text" name="address[]" />
This way php will receive an array of addresses.
Generally the practice would be to pass data as a DateTime with a "timezone" of UTC and then pass a TimeZoneInfo object and when you are ready to display the data, you use the TimeZoneInfo object to convert the UTC DateTime.
The other option is to set the DateTime with the current timezone, and then make sure the "timezone" is unknown for the DateTime object, then make sure the DateTime is again passed with a TimeZoneInfo that indicates the TimeZone of the DateTime passed.
As others have indicated here, it would be nice if Microsoft got on top of this and created one nice object to do it all, but for now you have to deal with two objects.
Modernizr can detect CSS 3D transforms, yeah. The truthiness of Modernizr.csstransforms3d
will tell you if the browser supports them.
The above link lets you select which tests to include in a Modernizr build, and the option you're looking for is available there.
Alternatively, as user356990 answered, you can use conditional comments if you're searching for IE and IE alone. Rather than creating a global variable, you can use HTML5 Boilerplate's <html>
conditional comments trick to assign a class:
<!--[if lt IE 7]> <html class="no-js lt-ie9 lt-ie8 lt-ie7"> <![endif]-->
<!--[if IE 7]> <html class="no-js lt-ie9 lt-ie8"> <![endif]-->
<!--[if IE 8]> <html class="no-js lt-ie9"> <![endif]-->
<!--[if gt IE 8]><!--> <html class="no-js"> <!--<![endif]-->
If you already have jQuery initialised, you can just check with $('html').hasClass('lt-ie9')
. If you need to check which IE version you're in so you can conditionally load either jQuery 1.x or 2.x, you can do something like this:
myChecks.ltIE9 = (function(){
var htmlElemClasses = document.querySelector('html').className.split(' ');
if (!htmlElemClasses){return false;}
for (var i = 0; i < htmlElemClasses.length; i += 1 ){
var klass = htmlElemClasses[i];
if (klass === 'lt-ie9'){
return true;
}
}
return false;
}());
N.B. IE conditional comments are only supported up to IE9 inclusive. From IE10 onwards, Microsoft encourages using feature detection rather than browser detection.
Whichever method you choose, you'd then test with
if ( myChecks.ltIE9 || Modernizr.csstransforms3d ){
// iframe or flash fallback
}
Don't take that ||
literally, of course.
It is possible to use filter predicates to specify which rows to include in the index.
From the documentation:
WHERE <filter_predicate> Creates a filtered index by specifying which rows to include in the index. The filtered index must be a nonclustered index on a table. Creates filtered statistics for the data rows in the filtered index.
Example:
CREATE TABLE Table1 (
NullableCol int NULL
)
CREATE UNIQUE INDEX IX_Table1 ON Table1 (NullableCol) WHERE NullableCol IS NOT NULL;
In another scenario just I would like to add is In my scenario, the name space was different for controller as it was mistake of copying controller from another project.
Like the other answer says, put the &
after the *
.
This brings up an interesting point that can be confusing sometimes: types should be read from right to left. For example, this is (starting from the rightmost *
) a pointer to a constant pointer to an int.
int * const *x;
What you wrote would therefore be a pointer to a reference, which is not possible.
Check for the name of the
templates
folder. it should be templates not template(without s).
None of the answers will solve your problem permanently. If you go to the path of adding XSD (From Xml menu, select "Create schema"), you will end up having problems with the package manager as it will clean up your packages.config file when you add a new package.
The best solution is just ignore by closing the file when you don't use it.
You missed underscore in argument document_root. But it's bad idea to use serve
in production. Use something like this instead:
import os
from django.conf import settings
from django.http import HttpResponse, Http404
def download(request, path):
file_path = os.path.join(settings.MEDIA_ROOT, path)
if os.path.exists(file_path):
with open(file_path, 'rb') as fh:
response = HttpResponse(fh.read(), content_type="application/vnd.ms-excel")
response['Content-Disposition'] = 'inline; filename=' + os.path.basename(file_path)
return response
raise Http404
Whenever you want to use ant thread safe version of ant collection object,take help of java.util.concurrent.* package. It has almost all concurrent version of unsynchronized collection objects. eg: for ArrayList, you have java.util.concurrent.CopyOnWriteArrayList
You can do Collections.synchronizedCollection(any collection object),but remember this classical synchr. technique is expensive and comes with performence overhead. java.util.concurrent.* package is less expensive and manage the performance in better way by using mechanisms like
copy-on-write,compare-and-swap,Lock,snapshot iterators,etc.
So,Prefer something from java.util.concurrent.* package
Cygwin includes grep. All the GNU tools amd Unix stuff works great on Windows if you install Cygwin.
This might sound really simplistic...
But this will center the div inside the div, exactly in the center in relation to left and right margin or parent container, but you can adjust percentage symmetrically on left and right.
margin-right: 10%;
margin-left: 10%;
Then you can adjust % to make it as wide as you want it.
It is not necessary.
No warning is generated if the variable does not exist. That means empty() is essentially the concise equivalent to !isset($var) || $var == false.
Based on official android docs, you can use this method in a Helper or Util class to get current battery percentage:
Java version:
public static int getBatteryPercentage(Context context) {
if (Build.VERSION.SDK_INT >= 21) {
BatteryManager bm = (BatteryManager) context.getSystemService(BATTERY_SERVICE);
return bm.getIntProperty(BatteryManager.BATTERY_PROPERTY_CAPACITY);
} else {
IntentFilter iFilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
Intent batteryStatus = context.registerReceiver(null, iFilter);
int level = batteryStatus != null ? batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, -1) : -1;
int scale = batteryStatus != null ? batteryStatus.getIntExtra(BatteryManager.EXTRA_SCALE, -1) : -1;
double batteryPct = level / (double) scale;
return (int) (batteryPct * 100);
}
}
Kotlin version:
fun getBatteryPercentage(context: Context): Int {
return if (Build.VERSION.SDK_INT >= 21) {
val bm = context.getSystemService(BATTERY_SERVICE) as BatteryManager
bm.getIntProperty(BatteryManager.BATTERY_PROPERTY_CAPACITY)
} else {
val iFilter = IntentFilter(Intent.ACTION_BATTERY_CHANGED)
val batteryStatus: Intent = context.registerReceiver(null, iFilter)
val level = batteryStatus?.getIntExtra(BatteryManager.EXTRA_LEVEL, -1)
val scale = batteryStatus?.getIntExtra(BatteryManager.EXTRA_SCALE, -1)
val batteryPct = level / scale.toDouble()
(batteryPct * 100).toInt()
}
}
If you installed the command line tools separately, delete them using:
sudo rm -rf /Library/Developer/CommandLineTools
If your PHP version is 5, try installing cURL by typing the following command in the terminal:
sudo apt-get install php5-curl
When you read in git tag
man page:
One important aspect of git is it is distributed, and being distributed largely means there is no inherent "upstream" or "downstream" in the system.
, that simply means there is no absolute upstream repo or downstream repo.
Those notions are always relative between two repos and depends on the way data flows:
If "yourRepo" has declared "otherRepo" as a remote one, then:
Note the "from" and "for": you are not just "downstream", you are "downstream from/for", hence the relative aspect.
The DVCS (Distributed Version Control System) twist is: you have no idea what downstream actually is, beside your own repo relative to the remote repos you have declared.
Basically:
In term of "flow of data", your repo is at the bottom ("downstream") of a flow coming from upstream repos ("pull from") and going back to (the same or other) upstream repos ("push to").
You can see an illustration in the git-rebase
man page with the paragraph "RECOVERING FROM UPSTREAM REBASE":
It means you are pulling from an "upstream" repo where a rebase took place, and you (the "downstream" repo) is stuck with the consequence (lots of duplicate commits, because the branch rebased upstream recreated the commits of the same branch you have locally).
That is bad because for one "upstream" repo, there can be many downstream repos (i.e. repos pulling from the upstream one, with the rebased branch), all of them having potentially to deal with the duplicate commits.
Again, with the "flow of data" analogy, in a DVCS, one bad command "upstream" can have a "ripple effect" downstream.
Note: this is not limited to data.
It also applies to parameters, as git commands (like the "porcelain" ones) often call internally other git commands (the "plumbing" ones). See rev-parse
man page:
Many git porcelainish commands take mixture of flags (i.e. parameters that begin with a dash '
-
') and parameters meant for the underlyinggit rev-list
command they use internally and flags and parameters for the other commands they use downstream ofgit rev-list
. This command is used to distinguish between them.
The 'c' means it's a character special file.
The local Maven repo tracks where artifacts originally came from using a file named "_maven.repositories" in the artifact directory. After removing it, the build worked. This answer fixed the problem for me.
In Python 3.7 and above, dictionaries are guaranteed to remember their key insertion order. The answer to this question summarizes the current state of affairs.
The OrderedDict
solution thus becomes obsolete and without any import statements we can simply issue:
>>> lst = [1, 2, 1, 3, 3, 2, 4]
>>> list(dict.fromkeys(lst))
[1, 2, 3, 4]
setTimeout(() => {
console.log('Hello Timeout!')
}, 3000);
setInterval(() => {
console.log('Hello Interval!')
}, 2000);
I would recommend using CSS for this. You should create a CSS rule to enforce the centering, for example:
.ui-helper-center {
text-align: center;
}
And then add the ui-helper-center
class to the table cells for which you wish to control the alignment:
<td class="ui-helper-center">Content</td>
EDIT: Since this answer was accepted, I felt obligated to edit out the parts that caused a flame-war in the comments, and to not promote poor and outdated practices.
See Gabe's answer for how to include the CSS rule into your page.
I don't believe the expression is sensical as it is.
Elvis means "if truthy, use the value, else use this other thing."
Your "other thing" is a closure, and the value is status != null
, neither of which would seem to be what you want. If status
is null, Elvis says true
. If it's not, you get an extra layer of closure.
Why can't you just use:
(it.description == desc) && ((status == null) || (it.status == status))
Even if that didn't work, all you need is the closure to return the appropriate value, right? There's no need to create two separate find
calls, just use an intermediate variable.
This is a really interesting article here. I'm considering implementing JS encryption for offering security when using local storage. It's absolutely clear that this will only offer protection if the device is stolen (and is implemented correctly). It won't offer protection against keyloggers etc. However this is not a JS issue as the keylogger threat is a problem of all applications, regardless of their execution platform (browser, native). As to the article "JavaScript Crypto Considered Harmful" referenced in the first answer, I have one criticism; it states "You could use SSL/TLS to solve this problem, but that's expensive and complicated". I think this is a very ambitious claim (and possibly rather biased). Yes, SSL has a cost, but if you look at the cost of developing native applications for multiple OS, rather than web-based due to this issue alone, the cost of SSL becomes insignificant.
My conclusion - There is a place for client-side encryption code, however as with all applications the developers must recognise it's limitations and implement if suitable for their needs, and ensuring there are ways of mitigating it's risks.
I managed to load an application.properties file in external path while using -jar option.
The key was PropertiesLauncher.
To use PropertiesLauncher, pom.xml file must be changed like this:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration> <!-- added -->
<layout>ZIP</layout> <!-- to use PropertiesLaunchar -->
</configuration>
</plugin>
</plugins>
</build>
For this, I referenced the following StackOverflow question: spring boot properties launcher unable to use . BTW, In Spring Boot Maven Plugin document(http://docs.spring.io/spring-boot/docs/1.1.7.RELEASE/maven-plugin/repackage-mojo.html), there is no mention that specifying ZIP triggers that PropertiesLauncher is used. (Perhaps in another document?)
After the jar file had been built, I could see that the PropertiesLauncher is used by inspecting Main-Class property in META-INF/MENIFEST.MF in the jar.
Now, I can run the jar as follows(in Windows):
java -Dloader.path=file:///C:/My/External/Dir,MyApp-0.0.1-SNAPSHOT.jar -jar MyApp-0.0.1-SNAPSHOT.jar
Note that the application jar file is included in loader.path.
Now an application.properties file in C:\My\External\Dir\config is loaded.
As a bonus, any file (for example, static html file) in that directory can also be accessed by the jar since it's in the loader path.
As for the non-jar (expanded) version mentioned in UPDATE 2, maybe there was a classpath order problem.
You can use ORDER BY ID DESC
, but it's WAY faster if you go that way:
SELECT * FROM bugs WHERE ID = (SELECT MAX(ID) FROM bugs WHERE user = 'me')
In case that you have a huge table, it could make a significant difference.
EDIT
You can even set a variable in case you need it more than once (or if you think it is easier to read).
SELECT @bug_id := MAX(ID) FROM bugs WHERE user = 'me';
SELECT * FROM bugs WHERE ID = @bug_id;
This is the way to include an external javascript file to you HTML markup.
<script type="text/javascript" src="/js/external-javascript.js"></script>
Where external-javascript.js
is the external file to be included. Make sure the path and the file name are correct while you including it.
<a href="javascript:showCountry('countryCode')">countryCode</a>
The above mentioned method is correct for anchor tags and will work perfectly. But for other elements you should specify the event explicitly.
Example:
<select name="users" onChange="showUser(this.value)">
Thanks, XmindZ
Just ran into this... I have a common library shared among multiple transpiled products. I was using symlinks with brunch to handle sharing things between the projects. When moving to webpack, this stopped working.
What did get things working was using webpack configuration to turn off symlink resolving.
i.e. adding this in webpack.config.js
:
module.exports = {
//...
resolve: {
symlinks: false
}
};
as documented here:
https://webpack.js.org/configuration/resolve/#resolvesymlinks

Combination of Mritunjay and Bartu's answers are full answer to this question. I copying the full example.
<input class="form-control" type="email" required="" placeholder="username"
oninvalid="this.setCustomValidity('Please Enter valid email')"
oninput="setCustomValidity('')"></input>
Here,
this.setCustomValidity('Please Enter valid email')" - Display the custom message on invalidated of the field
oninput="setCustomValidity('')" - Remove the invalidate message on validated filed.
A solution for me:
$old_ErrorActionPreference = $ErrorActionPreference
$ErrorActionPreference = 'SilentlyContinue'
if((Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue) -eq $null) {
WriteTraceForTrans "The session configuration MyShellUri is already unregistered."
}
else {
#Unregister-PSSessionConfiguration -Name "MyShellUri" -Force -ErrorAction Ignore
}
$ErrorActionPreference = $old_ErrorActionPreference
Or use try-catch
try {
(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue)
}
catch {
}

I have been waiting to see if Google would open a Keep API. When I discovered Google Tasks, and saw that it had an Android app, web app, and API, I converted over to Tasks. This may not directly answer your question, but it is my solution to the Keep API problem.
Tasks doesn't have a reminder alarm exactly like Keep. I can live without that if I also connect with the Calendar API.
A jQuery plugin based on M4N's answer
jQuery.fn.cssNumber = function(prop){
var v = parseInt(this.css(prop),10);
return isNaN(v) ? 0 : v;
};
So then you just use this method to get number values
$("#logo").cssNumber("top")

Most probly sun's administrative server.. It's usually bundled along with sun's directory and a few other webmin-ish stuff that is in the default installation
you might use default parameters in your function and then just pass the entire dataset itself, since the dataset is already a DOMStringMap Object
<div data-uid="aaa" data-name="bbb" data-value="ccc"
onclick="fun(this.dataset)">
<script>
const fun = ({uid:'ddd', name:'eee', value:'fff', other:'default'} = {}) {
//
}
</script>
that way, you can deal with any data-values that got set in the html tag, or use defaults if they weren't set - that kind of thing
maybe not in this situation, but in others, it might be advantageous to put all your preferences in a single data-attribute
<div data-all='{"uid":"aaa","name":"bbb","value":"ccc"}'
onclick="fun(JSON.parse(this.dataset.all))">
there are probably more terse ways of doing that, if you already know certain things about the order of the data
<div data-all="aaa,bbb,ccc" onclick="fun(this.dataset.all.split(','))">
I was facing same problem.. I downgraded webpack-dev-server to 2.5.1 version. Now everything is working fine .

I know that this question has an accepted answer but I thought I'd chip in with an alternative which uses array.reduce, seeing that summing an array is the canonical example for reduce:
$scope.sum = function(items, prop){
return items.reduce( function(a, b){
return a + b[prop];
}, 0);
};
$scope.travelerTotal = $scope.sum($scope.traveler, 'Amount');

You'll get it as part of a Visual Studio install (if you included the SDK), or in a standalone SDK install. It'll live somewhere like C:\program files\Microsoft Visual Studio 8\SDK\v2.0\Bin

http://msdn.microsoft.com/en-us/netframework/aa569263.aspx
If you are dealing with a lower level time object (I often just use integers), and don't want to write a custom filter for whatever reason, an approach I use is to pass the strftime function into the template as a variable, where it can be called where you need it.
For example:
import time
context={
'now':int(time.time()),
'strftime':time.strftime } # Note there are no brackets () after strftime
# This means we are passing in a function,
# not the result of a function.
self.response.write(jinja2.render_template('sometemplate.html', **context))
Which can then be used within sometemplate.html
:
<html>
<body>
<p>The time is {{ strftime('%H:%M%:%S',now) }}, and 5 seconds ago it was {{ strftime('%H:%M%:%S',now-5) }}.
</body>
</html>
Did you try using -removeObjectForKey
?

You could convert the dataframe to be a single column with stack
(this changes the shape from 5x3 to 15x1) and then take the standard deviation:
df.stack().std() # pandas default degrees of freedom is one
Alternatively, you can use values
to convert from a pandas dataframe to a numpy array before taking the standard deviation:
df.values.std(ddof=1) # numpy default degrees of freedom is zero
Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.
A couple of additional notes:
The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).
The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

Just a note with Xcode 4: in the organizer there are two different sections in the left pane:
Library > Provisioning profiles
Devices > your device > Provisioning profiles
I was always puttings my provisioning profiles into 2. and even after cleaning and installing properly it was not working. Then I discovered 1. and finally I found the refresh button. If you select 'Automatic device provisioning' in 1. and click on refresh, then everything got validated (no yellow warning in 2. anymore).
Hmm, I would use
window.location = 'http://localhost/index.html#?options=go_here';
I'm not exactly sure if that is what you mean.
Similar to @joran's answer. Reshape the df so that the prices for each product are in different columns:
xx <- reshape(df, idvar=c("skew","version","color"),
v.names="price", timevar="product", direction="wide")
xx will have columns price.p1, ... price.p4, so:
ggp <- ggplot(xx,aes(x=price.p1, y=price.p3, color=factor(skew))) +
geom_point(shape=19, size=5)
ggp + facet_grid(color~version)
gives the result from your image.
I wrapped the 'svg' tag in 'a' tag and put the onClick event in the 'a' tag
You need to make TestGetMethod async
too and attach await in front of GetIdList();
will unwrap the task to List<int>
, So if your helper function is returning Task make sure you have await as you are calling the function async
too.
public Task<List<int>> TestGetMethod()
{
return GetIdList();
}
async Task<List<int>> GetIdList()
{
using (HttpClient proxy = new HttpClient())
{
string response = await proxy.GetStringAsync("www.test.com");
List<int> idList = JsonConvert.DeserializeObject<List<int>>();
return idList;
}
}
Another option
public async void TestGetMethod(List<int> results)
{
results = await GetIdList(); // await will unwrap the List<int>
}
What worked for me now is:

See the following fiddle:
Well I too had the exactly same question. And everything was okay with my CSS
link. Why html was not loading the CSS
file was due to its position (as in my case).
Well I had my custom CSS
defined in the wrong place and that is why the webpage was not accessing it. Then I started to test and place the CSS link to different place and voila it worked for me.
I had read somewhere that we should place custom CSS
right after Bootstrap CSS
so I did but then it was not loading it. So I changed the position and it worked.
Hope this helps.
Thanks!
You can use the versionName
in XML resources, such as activity layouts. First create a string resource in the app/build.gradle
with the following snippet in the android
node:
applicationVariants.all { variant ->
variant.resValue "string", "versionName", variant.versionName
}
So the whole build.gradle
file contents may look like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion '24.0.0 rc3'
defaultConfig {
applicationId 'com.example.myapplication'
minSdkVersion 15
targetSdkVersion 23
versionCode 17
versionName '0.2.3'
jackOptions {
enabled true
}
}
applicationVariants.all { variant ->
variant.resValue "string", "versionName", variant.versionName
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.android.support:design:23.3.0'
compile 'com.android.support:support-v4:23.3.0'
}
Then you can use @string/versionName
in the XML. Android Studio will mark it red, but the app will compile without issues. For example, this may be used like this in app/src/main/res/xml/preferences.xml
:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory
android:title="About"
android:key="pref_key_about">
<Preference
android:key="pref_about_build"
android:title="Build version"
android:summary="@string/versionName" />
</PreferenceCategory>
</PreferenceScreen>
Your problem is on the call for the dialog
If you dont initialize the dialog, you don't have to pass "open" for it to show:
$("#dialog").dialog();
Also, this code needs to be on a $(document).ready();
function or be below the elements for it to work.
I recommend GPick:
sudo apt-get install gpick
Applications -> Graphics -> GPick
It has many more features than gcolor2 but is still extremely simple to use: click on one of the hex swatches, move your mouse around the screen over the colours you want to pick, then press the Space bar to add to your swatch list.
If that doesn't work, another way is to click-and-drag from the centre of the hexagon and release your mouse over the pixel that you want to sample. Then immediately hit Space to copy that color into the next swatch in rotation.
It also has a traditional colour picker (like gcolor2) in the bottom right-hand corner of the window to allow you to pick individual colours with magnification.

It just cuts off any text after 8191 characters. Well, actually, I got 8196 characters, and after 8196, then it just won't let me type any more.
Here's a script that will test how long of a statement you can use. Well, assuming you have gawk/awk installed.
echo rem this is a test of how long of a line that a .cmd script can generate >testbat.bat
gawk 'BEGIN {printf "echo -----";for (i=10;i^<=100000;i +=10) printf "%%06d----",i;print;print "pause";}' >>testbat.bat

You should use setStroke
to set a stroke of the Graphics2D
object.
The example at http://www.java2s.com gives you some code examples.
The following code produces the image below:
import java.awt.*;
import java.awt.geom.Line2D;
import javax.swing.*;
public class FrameTest {
public static void main(String[] args) {
JFrame jf = new JFrame("Demo");
Container cp = jf.getContentPane();
cp.add(new JComponent() {
public void paintComponent(Graphics g) {
Graphics2D g2 = (Graphics2D) g;
g2.setStroke(new BasicStroke(10));
g2.draw(new Line2D.Float(30, 20, 80, 90));
}
});
jf.setSize(300, 200);
jf.setVisible(true);
}
}
(Note that the setStroke
method is not available in the Graphics
object. You have to cast it to a Graphics2D
object.)
This post has been rewritten as an article here.
Installing the MoreLINQ package via Nuget, you can easily distinct object list by a property
IEnumerable<Catalogue> distinctCatalogues = catalogues.DistinctBy(c => c.CatalogueCode);
If your shell is tcsh or csh, you can set it in /etc/profile. Open terminal, "vim /etc/profile" and add the following line:
setenv CLASSPATH (insert your classpath here)
I don't think anyone has explained here that one issue is that you need "member pointers" rather than normal function pointers.
Member pointers to functions are not simply function pointers. In implementation terms, the compiler cannot use a simple function address because, in general, you don't know the address to call until you know which object to dereference for (think virtual functions). You also need to know the object in order to provide the this
implicit parameter, of course.
Having said that you need them, now I'll say that you really need to avoid them. Seriously, member pointers are a pain. It is much more sane to look at object-oriented design patterns that achieve the same goal, or to use a boost::function
or whatever as mentioned above - assuming you get to make that choice, that is.
If you are supplying that function pointer to existing code, so you really need a simple function pointer, you should write a function as a static member of the class. A static member function doesn't understand this
, so you'll need to pass the object in as an explicit parameter. There was once a not-that-unusual idiom along these lines for working with old C code that needs function pointers
class myclass
{
public:
virtual void myrealmethod () = 0;
static void myfunction (myclass *p);
}
void myclass::myfunction (myclass *p)
{
p->myrealmethod ();
}
Since myfunction
is really just a normal function (scope issues aside), a function pointer can be found in the normal C way.
EDIT - this kind of method is called a "class method" or a "static member function". The main difference from a non-member function is that, if you reference it from outside the class, you must specify the scope using the ::
scope resolution operator. For example, to get the function pointer, use &myclass::myfunction
and to call it use myclass::myfunction (arg);
.
This kind of thing is fairly common when using the old Win32 APIs, which were originally designed for C rather than C++. Of course in that case, the parameter is normally LPARAM or similar rather than a pointer, and some casting is needed.
That's a good problem. In order to solve that problem you will also have to disable ASLR otherwise the address of g() will be unpredictable.
Disable ASLR:
sudo bash -c 'echo 0 > /proc/sys/kernel/randomize_va_space'
Disable canaries:
gcc overflow.c -o overflow -fno-stack-protector
After canaries and ASLR are disabled it should be a straight forward attack like the ones described in Smashing the Stack for Fun and Profit
Here is a list of security features used in ubuntu: https://wiki.ubuntu.com/Security/Features You don't have to worry about NX bits, the address of g() will always be in a executable region of memory because it is within the TEXT memory segment. NX bits only come into play if you are trying to execute shellcode on the stack or heap, which is not required for this assignment.
Now go and clobber that EIP!
As Felix Kling said in the comments, provided your times are based on a 24 hour clock (and they should be if there's no AM/PM) and provided they are always in the format HH:MM:SS
you can do a direct string comparison:
var str1 = "10:20:45",
str2 = "05:10:10";
if (str1 > str2)
alert("Time 1 is later than time 2");
else
alert("Time 2 is later than time 1");
Your makefile should ideally be named makefile
, not make
. Note that you can call your makefile anything you like, but as you found, you then need the -f
option with make
to specify the name of the makefile. Using the default name of makefile
just makes life easier.
To install the prerequisites for GPU support in TensorFlow 2.1:
pip install tensorflow
.You can replace the first letter (preceded by a digit
) of each word using regex:
re.sub(r'(\d\w)', lambda w: w.group().upper(), '1bob 5sandy')
output:
1Bob 5Sandy
As some answers have pointed out, sometimes you really want to delete the local repository entirely, for example, there might be some artifacts that can't be purged as they are not anymore referenced by the pom.
If you want to have this deletion embedded in a maven phase, as for example clean
you can use the maven-clean-plugin
and access the repository through the settings, for example:
<plugin>
<inherited>false</inherited>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.1</version>
<executions>
<execution>
<phase>clean</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<echo>Base clean is attached to deleting local maven cache</echo>
<echo>${settings.localRepository}</echo>
</tasks>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<inherited>false</inherited>
<artifactId>maven-clean-plugin</artifactId>
<version>3.1.0</version>
<configuration>
<filesets>
<fileset>
<directory>${settings.localRepository}</directory>
</fileset>
</filesets>
</configuration>
</plugin>
LocalDate ld ....;
LocalDateTime ldtime ...;
ld.isEqual(LocalDate.from(ldtime));
What do you mean by delete
? In Python, removing a reference (or a name) can be done with the del
keyword, but if there are other names to the same object that object will not be deleted.
--> test = 3
--> print(test)
3
--> del test
--> print(test)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'test' is not defined
compared to:
--> test = 5
--> other is test # check that both name refer to the exact same object
True
--> del test # gets rid of test, but the object is still referenced by other
--> print(other)

Adm-zip has problems just compressing an existing archive https://github.com/cthackers/adm-zip/issues/64 as well as corruption with compressing binary files.
I've also ran into compression corruption issues with node-zip https://github.com/daraosn/node-zip/issues/4
node-archiver is the only one that seems to work well to compress but it doesn't have any uncompress functionality.
Even it is not a good way of doing what you want try this hint: var url = MUST BE A NUMER FIRST
function nextImage (){
url = url + 1;
location.href='http://mywebsite.com/' + url+'.html';
}
Validation is easy, text them a little code to type in. A CharField is a great way to store it. I wouldn't worry too much about canonicalizing phone numbers.
To make a wrapper class well being is not a easy job. To understand a wrapper class how it is designed by some others is also not a easy job. Because it is idea, not code. Only when you understand the idea, you can understand wrapper.
Unless the variable k
is defined, that's probably what's causing your trouble. Something like this will do what you want:
var new_tweets = { };
new_tweets.k = { };
new_tweets.k.tweet_id = 98745521;
new_tweets.k.user_id = 54875;
new_tweets.k.data = { };
new_tweets.k.data.in_reply_to_screen_name = 'other_user';
new_tweets.k.data.text = 'tweet text';
// Will create the JSON string you're looking for.
var json = JSON.stringify(new_tweets);
You can also do it all at once:
var new_tweets = {
k: {
tweet_id: 98745521,
user_id: 54875,
data: {
in_reply_to_screen_name: 'other_user',
text: 'tweet_text'
}
}
}
Bit late for reply but this should do the trick
Type myType = Type.GetType("AssemblyQualifiedName");
your assembly qualified name should be like this

I solved this problem by copying some colleague's .svn directory into mine and then updating my working copy. It was a nice, quick and clean solution.
With Kotlin, works with Gmail :
val i = Intent(Intent.ACTION_SENDTO).apply {
type = "text/html"
data = Uri.parse("mailto:")
putExtra(Intent.EXTRA_EMAIL, arrayOf(email))
putExtra(Intent.EXTRA_SUBJECT, subject)
putExtra(Intent.EXTRA_TITLE, subject)
}
if (packageManager != null && i.resolveActivity(packageManager) != null) {
startActivity(i)
}

To SUMIFS between dates, use the following:
=SUMIFS(B:B,A:A,">="&DATE(2012,1,1),A:A,"<"&DATE(2012,6,1))
To prevent inserting a record that exist already. I'd check if the ID value exists in the database. For the example of a Table created with an IDENTITY PRIMARY KEY:
CREATE TABLE [dbo].[Persons] (
ID INT IDENTITY(1,1) PRIMARY KEY,
LastName VARCHAR(40) NOT NULL,
FirstName VARCHAR(40)
);
When JANE DOE and JOE BROWN already exist in the database.
SET IDENTITY_INSERT [dbo].[Persons] OFF;
INSERT INTO [dbo].[Persons] (FirstName,LastName)
VALUES ('JANE','DOE');
INSERT INTO Persons (FirstName,LastName)
VALUES ('JOE','BROWN');
DATABASE OUTPUT of TABLE [dbo].[Persons] will be:
ID LastName FirstName
1 DOE Jane
2 BROWN JOE
I'd check if i should update an existing record or insert a new one. As the following JAVA example:
int NewID = 1;
boolean IdAlreadyExist = false;
// Using SQL database connection
// STEP 1: Set property
System.setProperty("java.net.preferIPv4Stack", "true");
// STEP 2: Register JDBC driver
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
// STEP 3: Open a connection
try (Connection conn1 = DriverManager.getConnection(DB_URL, USER,pwd) {
conn1.setAutoCommit(true);
String Select = "select * from Persons where ID = " + ID;
Statement st1 = conn1.createStatement();
ResultSet rs1 = st1.executeQuery(Select);
// iterate through the java resultset
while (rs1.next()) {
int ID = rs1.getInt("ID");
if (NewID==ID) {
IdAlreadyExist = true;
}
}
conn1.close();
} catch (SQLException e1) {
System.out.println(e1);
}
if (IdAlreadyExist==false) {
//Insert new record code here
} else {
//Update existing record code here
}

fork()
- creates a new child process, which is a complete copy of the parent process. Child and parent processes use different virtual address spaces, which is initially populated by the same memory pages. Then, as both processes are executed, the virtual address spaces begin to differ more and more, because the operating system performs a lazy copying of memory pages that are being written by either of these two processes and assigns an independent copies of the modified pages of memory for each process. This technique is called Copy-On-Write (COW).vfork()
- creates a new child process, which is a "quick" copy of the parent process. In contrast to the system call fork()
, child and parent processes share the same virtual address space. NOTE! Using the same virtual address space, both the parent and child use the same stack, the stack pointer and the instruction pointer, as in the case of the classic fork()
! To prevent unwanted interference between parent and child, which use the same stack, execution of the parent process is frozen until the child will call either exec()
(create a new virtual address space and a transition to a different stack) or _exit()
(termination of the process execution). vfork()
is the optimization of fork()
for "fork-and-exec" model. It can be performed 4-5 times faster than the fork()
, because unlike the fork()
(even with COW kept in the mind), implementation of vfork()
system call does not include the creation of a new address space (the allocation and setting up of new page directories).clone()
- creates a new child process. Various parameters of this system call, specify which parts of the parent process must be copied into the child process and which parts will be shared between them. As a result, this system call can be used to create all kinds of execution entities, starting from threads and finishing by completely independent processes. In fact, clone()
system call is the base which is used for the implementation of pthread_create()
and all the family of the fork()
system calls.exec()
- resets all the memory of the process, loads and parses specified executable binary, sets up new stack and passes control to the entry point of the loaded executable. This system call never return control to the caller and serves for loading of a new program to the already existing process. This system call with fork()
system call together form a classical UNIX process management model called "fork-and-exec".Here's a batch file, called base64encode.bat, that encodes base64.

To add to Heath's answer: It looks like Subversion 1.6 disabled storing passwords by default if it can't store them in encrypted form. You can allow storing unencrypted passwords by explicitly setting password-stores =
(that is, to the empty value) in ~/.subversion/config
.
To check which password store subversion uses, look in ~/.subversion/auth/svn.simple
. This contains several files, each a hash table with a simple key/value encoding. The svn:realmstring
in each file identifies which realm that file is for. If the file has
K 8
passtype
V 6
simple
then it stores the password in plain text somewhere in that file, in a K 8 password
entry. Else, it tries to use one of the configured password-stores
.
I know this is an old post but I also ran into this problem today. I found out that when I executed sudo softwareupdate -l
the Command Line Tools were listed as an update, so I installed them using sudo softwareupdate -i -a
.
Golang does not support implicit unpacking of an slice (unlike python) and that is the reason this would not work. Like the examples given above, we would need to workaround it.
One side note:
The implicit unpacking happens for variadic functions in go:
func varParamFunc(params ...int) {
}
varParamFunc(slice1...)
DOMDocument is a great choice. It's a module specifically designed for creating and manipulating XML documents. You can create a document from scratch, or open existing documents (or strings) and navigate and modify their structures.
$xml = new DOMDocument();
$xml_album = $xml->createElement("Album");
$xml_track = $xml->createElement("Track");
$xml_album->appendChild( $xml_track );
$xml->appendChild( $xml_album );
$xml->save("/tmp/test.xml");
To re-open and write:
$xml = new DOMDocument();
$xml->load('/tmp/test.xml');
$nodes = $xml->getElementsByTagName('Album') ;
if ($nodes->length > 0) {
//insert some stuff using appendChild()
}
//re-save
$xml->save("/tmp/test.xml");

catch(ParseException e)
{

return ILLEGAL_DATE; // Const = -2
}

I am writing specifically for Python newbies in a very simple way, though deep down Python does so many things.
Let’s start with the very basic:
Consider a list,
l = [1,2,3]
Let’s write an equivalent function:
def f():
return [1,2,3]
o/p of print(l): [1,2,3]
&
o/p of print(f()) : [1,2,3]
Let’s make list l iterable: In python list is always iterable that means you can apply iterator whenever you want.
Let’s apply iterator on list:
iter_l = iter(l) # iterator applied explicitly
Let’s make a function iterable, i.e. write an equivalent generator function.
In python as soon as you introduce the keyword yield
; it becomes a generator function and iterator will be applied implicitly.
Note: Every generator is always iterable with implicit iterator applied and here implicit iterator is the crux So the generator function will be:
def f():
yield 1
yield 2
yield 3
iter_f = f() # which is iter(f) as iterator is already applied implicitly
So if you have observed, as soon as you made function f a generator, it is already iter(f)
Now,
l is the list, after applying iterator method "iter" it becomes, iter(l)
f is already iter(f), after applying iterator method "iter" it becomes, iter(iter(f)), which is again iter(f)
It's kinda you are casting int to int(x) which is already int and it will remain int(x).
For example o/p of :
print(type(iter(iter(l))))
is
<class 'list_iterator'>
Never forget this is Python and not C or C++
Hence the conclusion from above explanation is:
list l ~= iter(l)
generator function f == iter(f)
As you say, local variables and references are stored on the stack. When a method returns, the stack pointer is simply moved back to where it was before the method started, that is, all local data is "removed from the stack". Therefore, there is no garbage collection needed on the stack, that only happens in the heap.
To answer your specific questions:
I am posting a complete example which I finally got working. Here I am reading in a file rooms/rooms.txt
from a script rooms/rooms.js
var fs = require('fs');
var path = require('path');
var readStream = fs.createReadStream(path.join(__dirname, '../rooms') + '/rooms.txt', 'utf8');
let data = ''
readStream.on('data', function(chunk) {
data += chunk;
}).on('end', function() {
console.log(data);
});
The split() method in javascript accepts two parameters: a separator and a limit. The separator specifies the character to use for splitting the string. If you don't specify a separator, the entire string is returned, non-separated. But, if you specify the empty string as a separator, the string is split between each character.
Therefore:
s.split('')
will have the effect you seek.
More information here
You should try using isinstance()
if isinstance(object, list):
## DO what you want
In your case
if isinstance(tmpDict[key], list):
## DO SOMETHING
To elaborate:
x = [1,2,3]
if type(x) == list():
print "This wont work"
if type(x) == list: ## one of the way to see if it's list
print "this will work"
if type(x) == type(list()):
print "lets see if this works"
if isinstance(x, list): ## most preferred way to check if it's list
print "This should work just fine"
The difference between isinstance()
and type()
though both seems to do the same job is that isinstance()
checks for subclasses in addition, while type()
doesn’t.
NetBeans has a built-in profiler.
I worked a little with RecyclerView
and still prefer ListView
.
Sure, both of them use ViewHolders
, so this is not an advantage.
A RecyclerView
is more difficult in coding.
A RecyclerView
doesn't contain a header and footer, so it's a minus.
A ListView
doesn't require to make a ViewHolder. In cases where you want to have a list with sections or subheaders it would be a good idea to make independent items (without a ViewHolder), it's easier and doesn't require separate classes.
Here is a short and fast in-memory solution that I came up with utilizing the Table Valued Constructors introduced in SQL Server 2008:
It will return 1,000,000 rows, however you can either add/remove CROSS JOINs, or use TOP clause to modify this.
;WITH v AS (SELECT * FROM (VALUES(0),(0),(0),(0),(0),(0),(0),(0),(0),(0)) v(z))
SELECT N FROM (SELECT ROW_NUMBER() OVER (ORDER BY v1.z)-1 N FROM v v1
CROSS JOIN v v2 CROSS JOIN v v3 CROSS JOIN v v4 CROSS JOIN v v5 CROSS JOIN v v6) Nums
Note that this could be quickly calculated on the fly, or (even better) stored in a permanent table (just add an INTO
clause after the SELECT N
segment) with a primary key on the N
field for improved efficiency.
For any complex application, I suggest to use an lxc container. lxc containers are 'something in the middle between a chroot on steroids and a full fledged virtual machine'.
For example, here's a way to build 32-bit wine using lxc on an Ubuntu Trusty system:
sudo apt-get install lxc lxc-templates
sudo lxc-create -t ubuntu -n my32bitbox -- --bindhome $LOGNAME -a i386 --release trusty
sudo lxc-start -n my32bitbox
# login as yourself
sudo sh -c "sed s/deb/deb-src/ /etc/apt/sources.list >> /etc/apt/sources.list"
sudo apt-get install devscripts
sudo apt-get build-dep wine1.7
apt-get source wine1.7
cd wine1.7-*
debuild -eDEB_BUILD_OPTIONS="parallel=8" -i -us -uc -b
shutdown -h now # to exit the container
Here is the wiki page about how to build 32-bit wine on a 64-bit host using lxc.
I just bumped into this problem, tried all above suggestions but still failed. Without repeat what have been suggested above, here are the things I (you) may be missing: In case you are using maven, likely you'll state the dependencies i.e:
<groupId>org.apache.derby</groupId>
<artifactId>derbyclient</artifactId>
<version>10.10.1.1</version>
Please be careful with the version. It must be compatible with the server instance you are running.
I solved my case by giving up on what maven dependencies provided and manually adding external jar from "%JAVA_HOME%\db\lib", the same source of my running server. In this case I'm testing using my Local.
So if you're testing with remote server instance, look for the derbyclient.jar that come with server package.
In your main activity:

YourFragment frag = (YourFragment) getChildFragmentManager().getFragments().get(viewPager.getCurrentItem());
frag.yourMethod(data); // Method for callback in YourFragment

Modifying Jeff's answer for optimal performance (thanks to performance test by Pierre Arnaud):
var type = typeof(MyType);
var implementsInterface = typeof(IMyInterface).IsAssignableFrom(type) && type.IsClass;
To find all types that implement an interface in a given Assembly
:
var implementations = typeof(TypeInTargetAssembly).Assembly.GetTypes()
.Where(t => typeof(IMyInterface).IsAssignableFrom(t) && t.IsClass);
Please Remember if you want to install python package/libraries for windows,
you should always consider Python unofficial Binaries
Step 1:
Search for your package, download dependent version 2.7 or 3.6 you can find it under Downloads/your_package_version.whl its called python wheel
Step 2:
Now install using pip,
pip install ~/Downloads/your_packae_ver.whl
this will install without any error.
If you paste the listing into your word processor instead of Notepad, (since each file name is in quotation marks with the full path name), you can highlight all the stuff you don't want on the first file, then use Find and Replace to replace every occurrence of that with nothing. Same with the ending quote (").
It makes a nice clean list of file names.
Note to under
connetionString =@"server=XXX;Trusted_Connection=yes;database=yourDB;";
Note: XXX = . OR .\SQLEXPRESS OR .\MSSQLSERVER OR (local)\SQLEXPRESS OR (localdb)\v11.0 &...
you can replace 'server' with 'Data Source'
too you can replace 'database' with 'Initial Catalog'
Sample:
connetionString =@"server=.\SQLEXPRESS;Trusted_Connection=yes;Initial Catalog=books;";
Check your AndroidManifest.xml file, see if the package name is correct. If you copied an example it is likely this is wrong and the source of your problem.
These answers all seem very complicated. If you are using this in a PowerShell script you can simply do this:
$name = 'Slim Shady'
Write-Host 'My name is'$name
It will output
My name is Slim Shady
Note how a space is put between the words for you
The conditional or operator is ||:
if (expr1 || expr2) {do stuff}
if (title == "User greeting" || title == "User name") {do stuff}
The conditional (the OR) and it's parts are boolean expressions.
MSDN lists the C# operators in precedence order here http://msdn.microsoft.com/en-us/library/6a71f45d.aspx . And the MSDN page for boolean expressions is http://msdn.microsoft.com/en-us/library/dya2szfk.aspx .
If you are just starting to learn programming, you should read up on Conditional Statements from an introductory text or tutorial. This one seems to cover most of the basics: http://www.functionx.com/csharp/Lesson10.htm .

I had some problems with anchor/hash-urls (including #) not reloading using the solution from Rex...
So I finally ended up by removing the hash part:
window.location = window.location.href.split("#")[0];
It amazes me how simple this is considering the depth of explanations... Here's all you need...
bool imLoopin = true;
while(imLoopin) {
switch(msg->state) {
case MSGTYPE: // ...
break;
// ... more stuff ...
case DONE:
imLoopin = false;
break;

}
LOL!! Really! That's all you need! One extra variable!
just edit wp_user table with your phpmyadmin, and choose MD5 on Function field then input your new password, save it (go button).
Replace Your onOptionsItemSelected
as:
@Override

// You can handle other cases Here.
default:
super.onOptionsItemSelected(item);
}
}
Here, I want to navigate from DashboardActivity
to SettingActivity

For a simple List structure the most efficient way seems to be using the Predicate RemoveAll implementation.
Eg.
workSpace.RoleAssignments.RemoveAll(x =>x.Member.Name == shortName);
The reasons are:
If you are stuck implementing this in a the pre c# 3.0 era. You have 2 options.
Eg.
List<int> list2 = new List<int>() ;
foreach (int i in GetList())
{
if (!(i % 2 == 0))
{
list2.Add(i);
}
}
list2 = list2;
Or
If you are removing stuff really frequently from a list, perhaps another structure like a HashTable (.net 1.1) or a Dictionary (.net 2.0) or a HashSet (.net 3.5) are better suited for this purpose.
In this particular case, Option 1 is better.
The guard statement (checking isDebugEnabled()
) is there to prevent potentially expensive computation of the log message when it involves invocation of the toString()
methods of various objects and concatenating the results.
In the given example, the log message is a constant string, so letting the logger discard it is just as efficient as checking whether the logger is enabled, and it lowers the complexity of the code because there are fewer branches.
Better yet is to use a more up-to-date logging framework where the log statements take a format specification and a list of arguments to be substituted by the logger—but "lazily," only if the logger is enabled. This is the approach taken by slf4j.
See my answer to a related question for more information, and an example of doing something like this with log4j.

In addition to adding @Transactional

I want to clarify some things here for the original poster which others have alluded to but haven't really explicitly stated. When you say that you want a Unique List, that is the very definition of an Ordered Set. Some other key differences between the Set Interface and the List interface are that List allows you to specify the insert index. So, the question is do you really need the List Interface (i.e. for compatibility with a 3rd party library, etc.), or can you redesign your software to use the Set interface? You also have to consider what you are doing with the interface. Is it important to find elements by their index? How many elements do you expect in your set? If you are going to have many elements, is ordering important?
If you really need a List which just has a unique constraint, there is the Apache Common Utils class org.apache.commons.collections.list.SetUniqueList which will provide you with the List interface and the unique constraint. Mind you, this breaks the List interface though. You will, however, get better performance from this if you need to seek into the list by index. If you can deal with the Set interface, and you have a smaller data set, then LinkedHashSet might be a good way to go. It just depends on the design and intent of your software.
Again, there are certain advantages and disadvantages to each collection. Some fast inserts but slow reads, some have fast reads but slow inserts, etc. It makes sense to spend a fair amount of time with the collections documentation to fully learn about the finer details of each class and interface.
You have to write in JSX:
<tbody>
{
objects.map((object, i) => (
<ObjectRow obj={object} key={i} />
));
}
</tbody>
gdb -ex=r --args myprogram arg1 arg2
-ex=r
is short for -ex=run
and tells gdb to run your program immediately, rather than wait for you to type "run" at the prompt. Then --args
says that everything that follows is the command and arguments, just as you'd normally type them at the commandline prompt.

Yes there is retainAll
check out this
Set<Type> intersection = new HashSet<Type>(s1);
intersection.retainAll(s2);
If the destination table does exist but you don't want to specify column names:
DECLARE @COLUMN_LIST NVARCHAR(MAX);
DECLARE @SQL_INSERT NVARCHAR(MAX);
SET @COLUMN_LIST = (SELECT DISTINCT
SUBSTRING(
(

First.. a couple missing use-cases here if we're talking about ways to inject anonymous code..
code.compile_command()
code.interact()
imp.load_compiled()
imp.load_dynamic()
imp.load_module()
__builtin__.compile()
loading C compiled shared objects? example: _socket?)
But, the real question is, what is your goal - are you trying to enforce some sort of security? Or are you just interested in whats being loaded.
If you're interested in security, the filename that is being imported via exec/execfile is inconsequential - you should use rexec, which offers the following:
This module contains the RExec class, which supports r_eval(), r_execfile(), r_exec(), and r_import() methods, which are restricted versions of the standard Python functions eval(), execfile() and the exec and import statements. Code executed in this restricted environment will only have access to modules and functions that are deemed safe; you can subclass RExec add or remove capabilities as desired.
However, if this is more of an academic pursuit.. here are a couple goofy approaches that you might be able to dig a little deeper into..
Example scripts:
./deep.py
print ' >> level 1'
execfile('deeper.py')
print ' << level 1'
./deeper.py
print '\t >> level 2'
exec("import sys; sys.path.append('/tmp'); import deepest")
print '\t << level 2'
/tmp/deepest.py
print '\t\t >> level 3'
print '\t\t\t I can see the earths core.'
print '\t\t << level 3'
./codespy.py
import sys, os
def overseer(frame, event, arg):
print "loaded(%s)" % os.path.abspath(frame.f_code.co_filename)
sys.settrace(overseer)
execfile("deep.py")
sys.exit(0)
Output
loaded(/Users/synthesizerpatel/deep.py)
>> level 1
loaded(/Users/synthesizerpatel/deeper.py)
>> level 2
loaded(/Users/synthesizerpatel/<string>)
loaded(/tmp/deepest.py)
>> level 3
I can see the earths core.
<< level 3
<< level 2
<< level 1
Of course, this is a resource-intensive way to do it, you'd be tracing all your code.. Not very efficient. But, I think it's a novel approach since it continues to work even as you get deeper into the nest. You can't override 'eval'. Although you can override execfile().
Note, this approach only coveres exec/execfile, not 'import'. For higher level 'module' load hooking you might be able to use use sys.path_hooks (Write-up courtesy of PyMOTW).
Thats all I have off the top of my head.
Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {

maven { url "https://jitpack.io" }
}}
and then add dependency

}

SparkButton button = new SparkButtonBuilder(context)
.setActiveImage(R.drawable.active_image)
.setInActiveImage(R.drawable.inactive_image)

.setImageSizePx(getResources().getDimensionPixelOffset(R.dimen.button_size))
.setPrimaryColor(ContextCompat.getColor(context, R.color.primary_color))

The :active pseudo-class is not the same as adding a class to style the element.
The :active CSS pseudo-class represents an element (such as a button) that is being activated by the user. When using a mouse, "activation" typically starts when the mouse button is pressed down and ends when it is released.
What we are looking for is a class, such as .active
, which we can use to style the navigation item.
For a clearer example of the difference between :active
and .active
see the following snippet:
li:active {_x000D_
background-color: #35495E;_x000D_
}_x000D_
_x000D_
li.active {_x000D_
background-color: #41B883;_x000D_
}
_x000D_
<ul>_x000D_
<li>:active (pseudo-class) - Click me!</li>_x000D_
<li class="active">.active (class)</li>_x000D_
</ul>
_x000D_
vue-router
automatically applies two active classes, .router-link-active
and .router-link-exact-active
, to the <router-link>
component.
router-link-active
This class is applied automatically to the <router-link>
component when its target route is matched.
The way this works is by using an inclusive match behavior. For example, <router-link to="/foo">
will get this class applied as long as the current path starts with /foo/
or is /foo
.
So, if we had <router-link to="/foo">
and <router-link to="/foo/bar">
, both components would get the router-link-active
class when the path is /foo/bar
.
router-link-exact-active
This class is applied automatically to the <router-link>
component when its target route is an exact match. Take into consideration that both classes, router-link-active
and router-link-exact-active
, will be applied to the component in this case.
Using the same example, if we had <router-link to="/foo">
and <router-link to="/foo/bar">
, the router-link-exact-active
class would only be applied to <router-link to="/foo/bar">
when the path is /foo/bar
.
Lets say we have <router-link to="/">
, what will happen is that this component will be active for every route. This may not be something that we want, so we can use the exact
prop like so: <router-link to="/" exact>
. Now the component will only get the active class applied when it is an exact match at /
.
We can use these classes to style our element, like so:
nav li:hover,
nav li.router-link-active,
nav li.router-link-exact-active {
background-color: indianred;
cursor: pointer;
}
The <router-link>
tag was changed using the tag
prop, <router-link tag="li" />
.
If we wish to change the default classes provided by vue-router
globally, we can do so by passing some options to the vue-router
instance like so:
const router = new VueRouter({
routes,
linkActiveClass: "active",
linkExactActiveClass: "exact-active",
})
<router-link>
)If instead we want to change the default classes per <router-link>
and not globally, we can do so by using the active-class
and exact-active-class
attributes like so:
<router-link to="/foo" active-class="active">foo</router-link>
<router-link to="/bar" exact-active-class="exact-active">bar</router-link>
Vue Router 3.1.0+ offers low level customization through a scoped slot. This comes handy when we wish to style the wrapper element, like a list element <li>
, but still keep the navigation logic in the anchor element <a>
.
<router-link
to="/foo"
v-slot="{ href, route, navigate, isActive, isExactActive }"
>
<li
:class="[isActive && 'router-link-active', isExactActive && 'router-link-exact-active']"
>
<a :href="href" @click="navigate">{{ route.fullPath }}</a>
</li>
</router-link>
Similar to the flex
answers above, this can also be done using CSS Grids. This gives you more scope to offset the title, and a more simple way of expanding the gap between the lines (using grid-template-columns
) and the content (using grid-gap
).
The benefits of this method over flex methods is the ease of being able to offset the lines, and additionally only needing to add in a gap between columns once (not twice, for each the :before
and :after
pseudo element). It is also much more syntactically cleaner and obvious IMO.
h1 {
display: grid;
grid-template-columns: 1fr auto 1fr;
align-items: center;
grid-gap: 1rem;
}
h1:before,
h1:after {
content: "";
display: block;
border-top: 2px solid currentColor;
}
h1.offset {
grid-template-columns: 1fr auto 3fr;
}
h1.biggap {
grid-gap: 4rem;
}
_x000D_
<h1>This is a title</h1>
<h1 class="offset">Offset title</h1>
<h1 class="biggap">Gappy title</h1>
<h1>
<span>Multi-line<br />title</span>
</h1>

It is not possible, most probably because 0xFFFFFFFF is greater than the maximum value for 32bit integers
I did a simple test with a formula, X-(X+1)=-1, and the largest value of X I can get to work on Safari, Opera and Firefox (tested on OS X) is 9e15. Here is the code I used for testing:

HTML: text/html
, full-stop.
XHTML: application/xhtml+xml
, or only if following HTML compatbility guidelines, text/html
. See the W3 Media Types Note.
XML: text/xml
, application/xml
(RFC 2376).
There are also many other media types based around XML, for example application/rss+xml
or image/svg+xml
. It's a safe bet that any unrecognised but registered ending in +xml
is XML-based. See the IANA list for registered media types ending in +xml
.
(For unregistered x-
types, all bets are off, but you'd hope +xml
would be respected.)

I thought I would contribute by providing a concrete example of the practical use of the scale function. Say you have 3 test scores (Math, Science, and English) that you want to compare. Maybe you may even want to generate a composite score based on each of the 3 tests for each observation. Your data could look as as thus:
student_id <- seq(1,10)
math <- c(502,600,412,358,495,512,410,625,573,522)
science <- c(95,99,80,82,75,85,80,95,89,86)
english <- c(25,22,18,15,20,28,15,30,27,18)
df <- data.frame(student_id,math,science,english)
Obviously it would not make sense to compare the means of these 3 scores as the scale of the scores are vastly different. By scaling them however, you have more comparable scoring units:
z <- scale(df[,2:4],center=TRUE,scale=TRUE)
You could then use these scaled results to create a composite score. For instance, average the values and assign a grade based on the percentiles of this average. Hope this helped!
Note: I borrowed this example from the book "R In Action". It's a great book! Would definitely recommend.
Expanding on the answer provided by @Mikko you can use a neat trick to speed things up without having to "know" your column classes ahead of time. Simply use read.xlsx
to grab a limited number of records to determine the classes and then followed it up with read.xlsx2
Example
# just the first 50 rows should do...
df.temp <- read.xlsx("filename.xlsx", 1, startRow=1, endRow=50)
df.real <- read.xlsx2("filename.xlsx", 1,
colClasses=as.vector(sapply(df.temp, mode)))
Assume the path of
Project A
C:\Projects\ProjectA
Project B
C:\Projects\ProjectB
and the dll of ProjectB is in
C:\Projects\ProjectB\bin\Debug\
To debug into ProjectB
from ProjectA
, do the following
B
's dll with dll's .PDB
to the ProjectA
's compiling directory. ProjectA
. When code reaches the part where you need to call dll's method or events etc while debugging, press F11
to step into the dll's code. NOTE : DO NOT MISS TO COPY THE .PDB FILE
Just set targetSdkVersion to 19. The notification icon will be colored. Then wait for Firebase to fix this issue.
Both John Conde's and ryeballar's answers are correct and will work.
If you want to get too geeky:
John's has the downside that it has to make two decisions per $digest loop (it has to decide whether to add/remove center
and it has to decide whether to add/remove left
), when clearly only one is needed.
Ryeballar's relies on the ternary operator which is probably going to be removed at some point (because the view should not contain any logic). (We can't be sure it will indeed be removed and it probably won't be any time soon, but if there is a more "safe" solution, why not ?)
So, you can do the following as an alternative:
ng-class="{true:'center',false:'left'}[page.isSelected(1)]"
You can just add an empty footer at the end then it will hide the empty cells but it will also look quite ugly:
tableView.tableFooterView = UIView()
There is a better approach: add a 1 point line at the end of the table view as the footer and the empty cells will also not been shown anymore.
let footerView = UIView()
footerView.frame = CGRect(x: 0, y: 0, width: tableView.frame.size.width, height: 1)
footerView.backgroundColor = tableView.separatorColor
tableView.tableFooterView = footerView
Here's what worked for me:
$a = Get-ChildItem \\server\XXX\Received_Orders\*.* | Where{$_.LastWriteTime -ge (Get-Date).AddDays(-7)}
if ($a = (Get-ChildItem \\server\XXX\Received_Orders\*.* | Where{$_.LastWriteTime -gt (Get-Date).AddDays(-7)}
#Im using the -gt switch instead of -ge
{}
Else
{
'STORE XXX HAS NOT RECEIVED ANY ORDERS IN THE PAST 7 DAYS'

Yes, it's possible. But first read, "What happens when I change my username?"
To change your username, click your profile picture in the top right corner, then click Settings
. On the left side, click Account
. Then click Change username
.
Give your inner div a width.
EXAMPLE
Change your CSS:
<style>
#outer { text-align: center; }
#inner { text-align: left; margin: 0 auto; }
.t { float: left; }
table { border: 1px solid black; }
#clearit { clear: left; }
</style>
To this:
<style>
#outer { text-align: center; }
#inner { text-align: left; margin: 0 auto; width:500px }
.t { float: left; }
table { border: 1px solid black; }
#clearit { clear: left; }
</style>
This would also work :
import 'package:http/http.dart' as http;
sendRequest() async {
Map data = {
'apikey': '12345678901234567890'
};
var url = 'https://pae.ipportalegre.pt/testes2/wsjson/api/app/ws-authenticate';
http.post(url, body: data)
.then((response) {
print("Response status: ${response.statusCode}");
print("Response body: ${response.body}");
});
}
Other answers are correct, especially the one by Jon Skeet, but outdated.
These old date-time classes have been supplanted by the java.time framework built into Java 8 and later.
If you simply want the current time in UTC, use the Instant
class.
Instant now = Instant.now();
EST
is not a time zone, as explained in the correct Answer by Jon Skeet. Such 3-4 letter codes are neither standardized nor unique, and further the confusion over Daylight Saving Time (DST). Use a proper time zone name in the "continent/region" format.
Perhaps you meant Eastern Standard Time in east coast of north America? Or Egypt Standard Time? Or European Standard Time?
ZoneId zoneId = ZoneId.of( "America/New_York" );
ZoneId zoneId = ZoneId.of( "Africa/Cairo" );
ZoneId zoneId = ZoneId.of( "Europe/Lisbon" );
Use any such ZoneId
object to get the current moment adjusted to a particular time zone to produce a ZonedDateTime
object.
ZonedDateTime zdt = ZonedDateTime.now( zoneId ) ;
Adjust that ZonedDateTime into a different time zone by producing another ZonedDateTime object from the first. The java.time framework uses immutable objects rather than changing (mutating) existing objects.
ZonedDateTime zdtGuam = zdt.withZoneSameInstant( ZoneId.of( "Pacific/Guam" ) ) ;
The docs give a pretty good explanation of the difference between apply()
and commit()
:
Unlike
commit()
, which writes its preferences out to persistent storage synchronously,apply()
commits its changes to the in-memorySharedPreferences
immediately but starts an asynchronous commit to disk and you won't be notified of any failures. If another editor on thisSharedPreferences
does a regularcommit()
while aapply()
is still outstanding, thecommit()
will block until all async commits are completed as well as the commit itself. AsSharedPreferences
instances are singletons within a process, it's safe to replace any instance ofcommit()
withapply()
if you were already ignoring the return value.
To read a whole line from a file into a string, use std::getline
like so:
std::ifstream file("my_file");
std::string temp;
std::getline(file, temp);
You can do this in a loop to until the end of the file like so:
std::ifstream file("my_file");
std::string temp;
while(std::getline(file, temp)) {
//Do with temp
}

Your "listen" directives are wrong. See this page: http://nginx.org/en/docs/http/server_names.html.
They should be
server {
listen 80;
server_name www.domain1.com;
root /var/www/domain1;
}
server {
listen 80;
server_name www.domain2.com;
root /var/www/domain2;
}
Note, I have only included the relevant lines. Everything else looked okay but I just deleted it for clarity. To test it you might want to try serving a text file from each server first before actually serving php. That's why I left the 'root' directive in there.

* (Xcode 7.2 / Deployment Target 7.0 / Landscape Orientation Only) *
I know is an old question but with Xcode 7.2 I'm still getting the message and I fixed with this:
1) Select PORTRAIT and both landscapes. Add "Launch Images Source" and "Launch Screen File"
2) In your Launch Image select iPhone "8.0 and Later" and "7.0 and Later".
3) Add this code in your appDelegate:

The documentation is hear https://laravel.com/docs/5.4/views#view-composers but i will break it down
Look for the directory app\Providers in the root directory of your application and create the file ComposerServiceProvider.php and copy and past the text below into it and save it.
<?php
namespace App\Providers;
use Illuminate\Support\Facades\View;
use Illuminate\Support\ServiceProvider;
class ComposerServiceProvider extends ServiceProvider
{
/**
* Register bindings in the container.
*
* @return void
*/
public function boot()
{
// Using class based composers...
View::composer(
'profile', 'App\Http\ViewComposers\ProfileComposer'
);
// Using Closure based composers...
View::composer('dashboard', function ($view) {
//
});
}
/**
* Register the service provider.
*
* @return void
*/
public function register()
{
//
}
}
From the root of your application open Config/app.php and look for the Providers section in the file and copy and past this 'App\Providers\ComposerServiceProvider', to the array.
By doing this, we have created the Composer Service Provider. When you run your application with the view Profile like so http://yourdomain/something/profile, the service provider ComposerServiceProvider is called and the class App\Http\ViewComposers\ProfileComposer is instantiated calling the method Composer due to the code below inside the boot method or function.
// Using class based composers...
View::composer(
'profile', 'App\Http\ViewComposers\ProfileComposer'
);
Go to the directory path app/Http
Create the directory called ViewComposers
Create the file ProfileComposer.php.
class ProfileComposer
{
/**
* The user repository implementation.
*
* @var UserRepository
*/
protected $users;
/**
* Create a new profile composer.
*
* @param UserRepository $users
* @return void
*/
public function __construct(UserRepository $users)
{
// Dependencies automatically resolved by service container...
$this->users = $users;
}
/**
* Bind data to the view.
*
* @param View $view
* @return void
*/
public function compose(View $view)
{
$view->with('count', $this->users->count());
}
}
Now go to your view or in this case Profile.blade.php and add
{{ $count }}
and that will show the count of users on the profile page.
To show the count on all pages change
// Using class based composers...
View::composer(
'profile', 'App\Http\ViewComposers\ProfileComposer'
);
To
// Using class based composers...
View::composer(
'*', 'App\Http\ViewComposers\ProfileComposer'
);
Setting the src
of a newly created iframe
in javascript does not trigger the HTML parser until the element is inserted into the document. The HTML is then updated and the HTML parser will be invoked and process the attribute as expected.
var iframe = document.createElement('iframe');
var html = '<body>Foo</body>';
iframe.src = 'data:text/html;charset=utf-8,' + encodeURI(html);
document.body.appendChild(iframe);
console.log('iframe.contentWindow =', iframe.contentWindow);
Also this answer your question it's important to note that this approach has compatibility issues with some browsers, please see the answer of @mschr for a cross-browser solution.

Your form doesn't contain any input tag other than the file so in your controller action you cannot expect to get anything else than the uploaded file (that's all that's being sent to the server). One way to achieve this would be to include a hidden tag containing the id of the model which will allow you to retrieve it from your datastore inside the controller action you are posting to (use this if the user is not supposed to modify the model but simply attach a file):
@using (Html.BeginForm("Uploadfile", "Containers", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.HiddenFor(x => x.Id)
<input type="file" name="file" id="file" />
<input type="submit" value="submit" />
}
and then in your controller action:
[HttpPost]
public ActionResult Uploadfile(int id, HttpPostedFileBase file)
{
Containers containers = Repository.GetContainers(id);
...
}
On the other hand if you wanted to allow the user to modify this model then you will need to include the proper input fields for each field of your model that you want to be sent to the server:
@using (Html.BeginForm("Uploadfile", "Containers", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.TextBoxFor(x => x.Prop1)
@Html.TextBoxFor(x => x.Prop2)
@Html.TextBoxFor(x => x.Prop3)
<input type="file" name="file" id="file" />
<input type="submit" value="submit" />
}
and then you will have the default model binder reconstruct this model from the request:
[HttpPost]
public ActionResult Uploadfile(Container containers, HttpPostedFileBase file)
{
...
}

- Download PCKeyboardHack and install it.
- Go to PCKeyboardHack in System Preferences.
- Enable ‘Change Caps Lock’ and set the keycode to 53.
This solution doesn't involve patching the keyboard driver, but gives you a Vim specific solution.
OS X supports mapping the Caps Lock key to a whole bunch of keys, but you have to do it 'by hand', editting .plist files. The process is described in this article. As addendum to that hint I suggest you first set Caps-Lock to None in the System Preferences, then you only need to change one value in the .plist file. Also, you can of course use the Property List Editor instead of going through the XML conversion steps.
The trick is to map the Caps Lock key to the Help key (code 6), which isn't on most keyboards. But if it is, it will be treated as the insert key, which you probably don't use anyway, since you ask about remapping your Caps Lock to prevent stretching your hands ;)
You can then map the Help and the Insert key to Esc in vim.
map <Help> <Esc>
map! <Help> <Esc>
map <Insert> <Esc>
map! <Insert> <Esc>
This will work for gvim (Vim.app). I didn't get it to work with vim in the Terminal and I haven't tested it with MacVim.
So, it's rather a complicated, half-baked solution or installing a third-party piece of hackery. Your pick ;)
Edit: Just noticed solution 3, if you're using MacVim you can use Ctrl, Option and Command as Esc. With the System Preferences it's trivial to map Caps Lock to one of those keys.

Presumably, those columns are integer columns - which will be the reason as the result of the calculation will be of the same type.
e.g. if you do this:
SELECT 1 / 2
you will get 0, which is obviously not the real answer. So, convert the values to e.g. decimal and do the calculation based on that datatype instead.
e.g.
SELECT CAST(1 AS DECIMAL) / 2
gives 0.500000
I solved this by changing transports from 'websocket' to 'polling'
var socket = io.connect('xxx.xxx.xxx.xxx:8000', {
transports: ['polling']
});
for the sake of it... here is a single line solution:
const x = [...new Set([['C', 'B'],['B', 'A']].reduce( (a, e) => a.concat(e), []))].sort()
// ['A', 'B', 'C']
Not particularly readable but it may help someone:
Set
.Set
to an array.sort()
function is applied to the new array.There is a big difference. Tasks are scheduled on the ThreadPool and could even be executed synchronous if appropiate.
If you have a long running background work you should specify this by using the correct Task Option.
You should prefer Task Parallel Library over explicit thread handling, as it is more optimized. Also you have more features like Continuation.

A couple of different ways to solve the problem:
Just replace Environment.Exit with return. The compiler knows that return ends the method, but doesn't know that Environment.Exit does.
static void Main(string[] args) {
if(args.Length != 0) {
if(Byte.TryParse(args[0], out maxSize))
queue = new Queue(){MaxSize = maxSize};
else
return;
} else {
return;
}
Of course, you can really only get away with that because you're using 0 as your exit code in all cases. Really, you should return an int instead of using Environment.Exit. For this particular case, this would be my preferred method
static int Main(string[] args) {
if(args.Length != 0) {
if(Byte.TryParse(args[0], out maxSize))
queue = new Queue(){MaxSize = maxSize};
else
return 1;
} else {
return 2;
}
}
Initialize queue to null, which is really just a compiler trick that says "I'll figure out my own uninitialized variables, thank you very much". It's a useful trick, but I don't like it in this case - you have too many if branches to easily check that you're doing it properly. If you really wanted to do it this way, something like this would be clearer:
static void Main(string[] args) {
Byte maxSize;
Queue queue = null;
if(args.Length == 0 || !Byte.TryParse(args[0], out maxSize)) {
Environment.Exit(0);
}
queue = new Queue(){MaxSize = maxSize};
for(Byte j = 0; j < queue.MaxSize; j++)
queue.Insert(j);
for(Byte j = 0; j < queue.MaxSize; j++)
Console.WriteLine(queue.Remove());
}
Add a return statement after Environment.Exit. Again, this is more of a compiler trick - but is slightly more legit IMO because it adds semantics for humans as well (though it'll keep you from that vaunted 100% code coverage)
static void Main(String[] args) {
if(args.Length != 0) {
if(Byte.TryParse(args[0], out maxSize)) {
queue = new Queue(){MaxSize = maxSize};
} else {
Environment.Exit(0);
return;
}
} else {
Environment.Exit(0);
return;
}
for(Byte j = 0; j < queue.MaxSize; j++)
queue.Insert(j);
for(Byte j = 0; j < queue.MaxSize; j++)
Console.WriteLine(queue.Remove());
}
I recently found this App called Icon Set Creator in the App Store which is free, without ads, updated on new changes, straight forward and works just fine for every possible icon size in OSX, iOS and WatchOS:

Try the following code:
Edittext_name.setKeyListener(DigitsKeyListener.getInstance("0123456789"));
It will allow you to enter just numbers. You cannot enter chars.
if you want to enter chars, not numbers, you can edit the values between the quotes inside getInstance
.
Here's an improvement, grabbing just the directory to stdout:
java -XshowSettings:properties -version 2>&1 \

Something like this?

@Richie Cotton has a pretty good answer above. I can only add that this page provides some examples. Try the following:

The question title is too wide and the author's need is more specific. In my case, I needed to extract all elements from nested list like in the example below:
input -> [1,2,[3,4]]
output -> [1,2,3,4]
The code below gives me the result, but I would like to know if anyone can create a simpler answer:
def get_elements_from_nested_list(l, new_l):
if l is not None:
e = l[0]
if isinstance(e, list):
get_elements_from_nested_list(e, new_l)
else:
new_l.append(e)
if len(l) > 1:
return get_elements_from_nested_list(l[1:], new_l)
else:
return new_l
l = [1,2,[3,4]]
new_l = []
get_elements_from_nested_list(l, new_l)
I think registering for the UIApplicationWillEnterForegroundNotification is risky as you may end up with more than one controller reacting to that notification. Nothing garanties that these controllers are still visible when the notification is received.
Here is what I do: I force call viewDidAppear on the active controller directly from the App's delegate didBecomeActive method:
Add the code below to - (void)applicationDidBecomeActive:(UIApplication *)application
UIViewController *activeController = window.rootViewController;
if ([activeController isKindOfClass:[UINavigationController class]]) {
activeController = [(UINavigationController*)window.rootViewController topViewController];
}
[activeController viewDidAppear:NO];
